48 PCS 3D Printer POM Pulley Wheel Set with Rubber Bearing Included 16 PCS POM Wheel 16 PCS Eccentric Spacer 16 PCS Round Column for Creality Anycubic Anet Series 3D Printer Ender 3

Works as intended, super smooth action. Just take your time and install then right.

The spacers and eccentric hex spacers are not the correct size for an Anycubic Kobra Plus. Maybe I misunderstood the description when I read the Anycubic brand. Just reused the old ones. Only thing is I could have just bought the wheel and bearings and not had the extra pieces I didn't need. Will see how well they wear compared to OEM wheels.

Great product for the price. The included spaces are too small to use on my Ender 3, but I just reused the stock ones which didn't have any wear at all. My bed is nice and tight again with no wobble.

Wheels are good, spacers and adjustors are too short (2mm too short) for Ender 3 pro.Could have just bought the wheels for about half the price. Should have read the reviews.

I had a bearing on my engraver that I suspected of being bad and I needed some extra eccentric spacers for another project, so this package was a good value for me. All worked out great!

excelente compra, buena calidad, se recomienda el vendedor.

My original POM wheels and a set of new POM wheels that came with some carriage support plates I bought (not from this company) all use the 625ZZ (metal sealed) bearings. They all had an "icky" resistance to them where the wheel seems to want to drag more than roll. After doing some digging around I saw that 625-2RS (rubber sealed) bearings tend to perform better than the ZZ variant.This was the only item I found that had POM wheels with 2RS bearings. While I have not speak on this company's ZZ bearing-based wheels, I can tell you that there is a VERY noticeable difference in the way the wheel moves on the 2RS bearing. They roll significantly better and have a longer free spin. The 2RS wheels can be maintained since the rubber seal can be removed to access the bearing components. Because of the amount of free spin these wheels had compared to the ZZ variant, I removed a seal on one to make sure it had lubrication. The lubrication was there and it was incredibly clean (almost transparent).

I have ordered these in the past to build my own laserbeds. Always the best quality, always arrive very quickly. TOP NOTCH! I believe most DIYers would whole heartedly agree. :-) I couldn't be happier with any other POM wheels.
